Not sure how much detail you want in your filenames but this is how I like my filenames....
If I have multi disc sets then I append the discnumber as in the format below. Inversely, no multi disc just %track% %title%
The Album "Days of Rising Doom" from AINA. Disc 2, Track 2 would look like this:
2-17 The Beast Within
(I also number all tracks sequentially from 1 - number of tracks ... this seems to make it easier for some apps in the sorting process I have found)
I suppose the mechanics of it may be a bit confusing. But if you have the field %totaldiscs% or an equivalent this will work in your action group ...
- Field: _FILENAME
- Format String: $ifgreater(%totaldiscs%,1,$left(%discnumber%,2)-$num(%track%,2) %title%,$num(%track%,2) %title%)
Hope this helps you....
